The price per kWh covers generating electricity, moving it over long-distance transmission lines and delivering it through local distribution lines. States that rely on cheap hydropower or local fuel tend to pay less; states that import fuel or have high grid costs pay more. Weather, demand and state policies also play a part. Read more in why electricity prices vary by state.
Each state's average is the revenue utilities collected from homes divided by the kWh they sold (EIA Form 861M). The 12-month figure is weighted by how much electricity was sold each month, so it smooths out seasonal swings. Your own rate depends on your utility or supplier and your plan.
In most states one regulated utility supplies and delivers your power. In states with retail choice you can buy the electricity itself from a competing supplier, while the local utility still delivers it. States with retail choice in our data: Texas, Ohio, Pennsylvania, Illinois, New York, New Jersey, Maryland, Massachusetts, Connecticut, Maine, New Hampshire, Rhode Island, Delaware, District of Columbia.

Average rate = residential revenue ÷ residential kWh sold, from EIA Form 861M. The 12-month average is weighted by kWh sold each month.
A kilowatt-hour is 1,000 watts used for one hour – for example a 1,000-watt heater running for an hour. Electric bills charge per kWh.
